Crossing Over Exchange of chromosomal segments between a pair of homologous chromosomes during prophase I of meiosis. (Genetic variety)

Third main stage of the cell cycle, during which the cell’s cytoplasm divides, creating a new cell.

Cytokinesis Third main stage of the cell cycle, during which the cell’s cytoplasm divides, creating a new cell.

First stage of mitosis, during which the cell’s chromatin condenses into chromosomes (Nucleus disappears & Chromosomes become visible).

Prophase First stage of mitosis, during which the cell’s chromatin condenses into chromosomes (Nucleus disappears & Chromosomes become visible).

Cell with half the number of chromosomes (n) as a diploid (2n) cell. (Sperm & eggs)

Haploid Cell with half the number of chromosomes (n) as a diploid (2n) cell. (Sperm & eggs)

Second state of the cell cycle during which the cell’s replicated DNA divides and two genetically identical diploid daughter cells are produced.

Mitosis Second state of the cell cycle during which the cell’s replicated DNA divides and two genetically identical diploid daughter cells are produced.

Asexual form of reproduction used by some prokaryotes in which a cell divides into two genetically identical cells. (How bacteria reproduce)

Binary Fission Asexual form of reproduction used by some prokaryotes in which a cell divides into two genetically identical cells. (How bacteria reproduce)

Second stage of mitosis in which motor proteins pull sister chromatids to the cell’s equator (middle)

Metaphase Second stage of mitosis in which motor proteins pull sister chromatids to the cell’s equator (middle)

A haploid sex cell, formed during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg. (Sperm & eggs)

Gamete A haploid sex cell, formed during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg. (Sperm & eggs)

Process of cellular reproduction, occurring in three main stages – Interphase (growth), mitosis (cell division), and cytokinesis (cytoplasm division)

Cell Cycle Process of cellular reproduction, occurring in three main stages – Interphase (growth), mitosis (cell division), and cytokinesis (cytoplasm division)

Reduction division process, occurring only in reproductive cells (sperm & eggs), in which one diploid (2n) cell produces four haploid (n) cells that are not genetically identical.

Meiosis Reduction division process, occurring only in reproductive cells (sperm & eggs), in which one diploid (2n) cell produces four haploid (n) cells that are not genetically identical.

Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell. (Chromosomes move across the cell)

Anaphase Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell. (Chromosomes move across the cell)

Having two copies of each chromosome (2n). (Body/Somatic Cells)

Diploid Having two copies of each chromosome (2n). (Body/Somatic Cells)

First stage of the cell cycle, during which a cell grows, matures, and replicates it DNA.

Interphase First stage of the cell cycle, during which a cell grows, matures, and replicates it DNA.

Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.

Telophase Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.
